On a generalization of a Greguš fixed point theorem

Czechoslovak Mathematical Journal

Similarity:

Let $C$ be a closed convex subset of a complete convex metric space $X$ . In this paper a class of selfmappings on $C$ , which satisfy the nonexpansive type condition $(2)$ below, is introduced and investigated. The main result is that such mappings have a unique fixed point.

Some similarity between contractions and Kannan mappings.

Similarity:

In this paper we prove two fixed point theorems for generalized contractions with constants in complete metric space, which are generalizations of very recent results of Kikkawa and Suzuki.
